#emc | Logs for 2010-02-06

Back[01:00:59]<frysteev> not to ask a loaded question in here, but comparison wise from emc to mach3, [01:01:13]<frysteev> is it worth it to have mach3 on the machine at all? [01:02:31]<cradek> I can't imagine why you'd want both, seeing as how they even run on different OSes [01:02:50]<cradek> maybe you can elaborate on your question? [01:03:04]<frysteev> well dual boot, [01:03:19]<frysteev> i guess im wondering for any corss compatability.. [01:03:22]<frysteev> cross. [01:03:29]<cradek> with what? [01:03:34]<frysteev> i like emc form what ive played with it.. [01:03:47]<frysteev> but i keep running into mach3 users who dont even know what linux is [01:04:10]<cradek> well, that seems pretty irrelevant to me [01:04:51]<frysteev> i guess im just second guessing my software choices :P [01:05:19]<cradek> maybe you should try both? [01:05:35]<cradek> obviously people here will tell you emc is better [01:06:13]<cradek> I've never used mach3 and I do not have or use windows... [01:06:23]<frysteev> ill be quiet.. [01:06:35]<danimal_garage> lol hit a nerve [01:06:36]<frysteev> id rather use an opensource product, [01:06:57]<frysteev> am i missing anything by using emc is i guess what im wondering [01:07:07]<danimal_garage> i doubt it [01:07:21]<cradek> for some kinds of machines, like high powered velocity mode servo machines, emc is very clearly better (IMO). mach3 may have some nice features for hobbyists that emc doesn't, I'm not sure [01:07:37]<danimal_garage> i think if anything, mach might be easier to configure for basic stuff [01:07:39]<cradek> if you try both, report back and let us know :-) [01:08:34]<danimal_garage> i was scared away from mach because i heard it wasnt as stable [01:08:44]<danimal_garage> but that might just be rumours [01:09:38]<danimal_garage> havent come across any limitations with emc yet [01:10:06]<frysteev> cool [01:10:07]<danimal_garage> just a little difficult for the n00bs IMO [01:10:13]<danimal_garage> to configure [01:10:20]<frysteev> i have only used emc in a 2d enviroment for a laser engraver [01:10:31]<danimal_garage> <-----n00b [01:10:57]<danimal_garage> cool [01:11:05]<danimal_garage> what'd you use for a laser? [01:11:17]<danimal_garage> i'd love to make a laser engraver [01:11:38]<frysteev> was a uls system that had a dead controller, so it was rebuilt and hooked up to emc [01:11:47]<danimal_garage> nice [01:12:09]<frysteev> and im working on setting up a small cnc table i got. [01:12:30]<jackc> emc will do anything from tiny mills and lathes to 6-axis robot arms and tetropods and such [01:12:53]<danimal_garage> and big mills and lathes :) [01:13:01]<Jymmm> frysteev: yo [01:13:14]<frysteev> hey Jymmm [01:13:30]<Jymmm> you rang/ [01:13:32]<Jymmm> ? [01:13:34]<frysteev> got the t slot table installed, [01:13:39]<frysteev> i forget why now.. [01:13:41]<Jymmm> cool beans [01:13:54]<frysteev> oh yeah, wondering about which end for home switches [01:14:06]<Jymmm> each end [01:14:10]<frysteev> just installed the emc ubuntu distro.. pretty easy [01:14:25]<frysteev> well limit switches at both ends,, [01:14:27]<Jymmm> oh home, not limit....... um..... [01:14:35]<Jymmm> On mine... [01:14:55]<Jymmm> XY 0,0 is the lower (closeest to you) left corner [01:14:55]<frysteev> well i was planning on doing only a combo home/limit switch at one end [01:15:57]<frysteev> ok [01:16:11]<cradek> you can home to either end, doesn't matter [01:16:23]<cradek> (Z should home upward for obvious reasons) [01:16:27]<ds3> frysteev: you got EMC running with a laser? [01:16:47]<frysteev> not me personally. but i was involved with it [01:16:55]<ds3> what kind of laser was it? [01:17:12]<frysteev> andrew's blog post http://www.andrewkilpatrick.org/blog/?page_id=914[01:17:28]<frysteev> its the same one Optic, in here has chatted about [01:17:41]<Jymmm> X,Y [01:17:41]<Jymmm> 24,0 -- 24,24 [01:17:43]<Jymmm> | | [01:17:45]<Jymmm> 0,0 __ 0,24 [01:18:05]<ds3> I see [01:18:05]<Jymmm> wait, I fscked up [01:18:40]<cradek> Jymmm: close... [01:19:51]<frysteev> if i do limit switches at both ends can i also use those to home? [01:20:01]<cradek> yes [01:20:12]<Jymmm> X,Y [01:20:12]<Jymmm> 0,24 --- 24,24 [01:20:13]<Jymmm> | | [01:20:15]<Jymmm> Y | [01:20:17]<Jymmm> | | [01:20:19]<Jymmm> 0,0 -X- 24,0 [01:20:26]<cradek> * cradek claps [01:20:30]<Jymmm> lol [01:20:45]<ds3> frysteev: if I read it right, you still have the Audrino doing the PWM in the "finish" setup? [01:20:47]<frysteev> i would prefer to have limit switches on both ends... [01:20:56]<frysteev> ds3: i believe so [01:21:12]<ds3> oh [01:21:30]<frysteev> i have made a tun of stuff on the laser, but i wasnt involved in that part much [01:21:33]<ds3> guess not many people are using EMC to do the PWM [01:22:03]<frysteev> i think they did it on the arduino as more of a failsafe if emc messed up [01:22:19]<ds3> oh [01:25:23]<frysteev> we were all noobs to cnc and emc and playing it safe [01:25:32]<frysteev> that laser is also installed in a bathroom [01:25:38]<ds3> I noticed that [01:26:38]<ds3> frysteev: how did you generate the Gcode for it? [01:27:19]<frysteev> since most of the stuff is 2d [01:27:34]<frysteev> i use inkscape to draw it. then there is some gcode converters [01:29:15]<ds3> so most of your stuff on there is art? [01:29:42]<frysteev> no [01:29:52]<frysteev> but its all 2d. [01:30:05]<frysteev> inkscape has a cool plugin for making gears [01:30:06]<ds3> then how do you hand the kerf adjustment? [01:30:15]<frysteev> ?? [01:30:52]<ds3> if you draw a 1"x1" box and send it, doesn't it cut right on the 1" mark? so the resultant peice will be 1"-(2*width of kerf), right? [01:31:10]<frysteev> yes. [01:31:25]<ds3> for actual parts, don't you have to adjust for it? [01:31:30]<frysteev> basically the stuff that is made on there is made with that in mind [01:31:45]<frysteev> and the beam of the laser is much smaller then a tool head [01:31:46]<ds3> gotcha, you drew it a bit bigger to account for it, right? [01:31:57]<frysteev> yeah [01:32:04]<frysteev> but most of the time i dont worry about it [01:32:14]<frysteev> what do you guys use for cad programs? [01:32:16]<ds3> I had a laser cutting shop do that and the parts came back undersize...drove me crazy :( [01:33:42]<frysteev> eep [01:36:05]<frysteev> i need to figure out the cad to emc workflow [01:38:18]<ds3> me too... but I need to figure out the emc to machine side first [01:40:30]<frysteev> ds3: ideas? [01:40:53]<ds3> frysteev: One thought (if you will stomach windows) is sheetcam -> emc [01:41:10]<ds3> sheetcam can accept DXF's and most modelers will generate DXFs [01:41:24]<frysteev> hmm [01:41:29]<ds3> so the overall path is something like ... Alibre -> SheetCAM -> EMC [01:41:56]<frysteev> brb [02:04:53]<frysteev> back [02:07:03]<Optic> is sheetcam good? [02:08:01]<Optic> it looks like exactly what I've been looking for :) [02:09:26]<frysteev> ya it looks cool [02:12:11]<Optic> maybe i'll try sheetcam on the laser this weekend [02:14:26]<Optic> watching the youtube vids [02:14:49]<frysteev> Optic: lemmie know if you want company at the lab for figuring it out [02:15:08]<Optic> sure, not sure of my plan but i'll let you know for sure [02:16:53]<ds3> sheetcam is the cheapest of the cams that seems to have reasonable feature set [02:17:14]<Optic> i've been using the python dxf2gcode [02:17:19]<Optic> and it's not so awesome :) [02:17:25]<ds3> and that generates output on centerlines [02:17:33]<ds3> I want automatic "cutter comp" [02:18:05]<ds3> have either of you tried cutting acrylic on that laser? [02:18:33]<Optic> oh yeah [02:18:35]<Optic> lots :) [02:18:47]<ds3> how thick have you been able to cut at 25W? [02:18:52]<Optic> about 1/4" [02:18:55]<frysteev> ya [02:19:00]<frysteev> over that and its not pretty [02:19:07]<ds3> single pass? [02:19:11]<Optic> y3p [02:19:26]<Optic> at about 1ips [02:19:27]<ds3> are you using compressed air to blow away the fumes from the lenses? [02:19:58]<Optic> there's a laminar flow over the table [02:20:47]<ds3> that's nice... sounds advantagous to start with a US chassis [02:23:05]<Optic> it's a nice unit [02:23:56]<ds3> the import lasers claim a higher power but lack the nicer features [02:24:55]<Optic> i saw a cheap chinese one, the build quality was terrible [02:25:18]<Optic> optics that were hot-glued in place, terrible ventilation, etc [02:25:21]<ds3> the smaller ones don't have an airflow setup [02:25:32]<Optic> it had a PC-style muffin fan [02:25:51]<Optic> it also didn't have an adjustable-height table, I don't know how they expected you to focus it [02:25:53]<ds3> that's better then what I have seen [02:26:03]<Optic> our table has a height drive [02:26:05]<ds3> those things are fix focus [02:26:16]<Optic> material isn't fixed thickness though :) [02:26:18]<frysteev> hmm [02:26:27]<ds3> have you looked at how the epilogue units work? are they similar to your USL setup? [02:26:29]<frysteev> im trying to figure out the pin config in emc.. [02:27:00]<frysteev> my stepper board has pins labeled for enable x,y and z but i cant figure out the corisponding emc function [02:27:54]<ds3> thought you guys built one from FET's? [02:28:10]<frysteev> this is for my personal one [02:29:01]<ds3> frysteev: you got another laser skeleton? [02:29:25]<frysteev> no this is for my cnc router [02:29:56]<frysteev>http://www.flickr.com/photos/34832969@N03/4330863953/in/photostream/[02:30:16]<ds3> ball screw? [02:30:19]<frysteev>http://www.cncgeeker.com/index.php?main_page=product_info&cPath=1&products_id=41&zenid=d759ff7a951131ffebb233ec7a06be6f[02:30:24]<frysteev> i have that coming [02:30:38]<frysteev> but cant figure out the 'enable' pins [02:30:41]<ds3> oh so what's on that picture is acme? [03:07:28]<terrylm> Hi [03:12:20]<terrylm> I have all the hardware in place now for the tool turret on my lathe. Can it be implemented as a kind of invisable rotary axis? [03:13:51]<terrylm> Or would there be some other facility, like the way the spindle is handled? [03:14:08]<ries> does John Thornton come here? [03:14:27]<terrylm> Don't know. new myself. [03:14:39]<ries> jt-plasma: are you John Thornton ?? :) [03:14:55]<terrylm> no, Terry Mackintosh [03:14:57]<ries> terrylm: I don't have a lathe... [03:15:13]<terrylm> what do you have? [03:15:19]<ries> gantry router [03:15:25]<terrylm> neat [03:16:02]<terrylm> A friend of mine has one, 4x8, makes speaker enclosers with it [03:16:04]<terrylm> . [03:16:21]<terrylm> enclosures [03:17:04]<ries> mine is he same size... Planning to build electrostatics again [03:17:24]<terrylm> What is electrostatics? [03:17:42]<ries> electrostatic loudspeakers [03:17:51]<terrylm> Oh. [03:19:00]<ries> Ahhh jthornton is in teh room :) [03:19:07]<ries> will page him tomorrow [03:19:35]<terrylm> Is you router working now? [03:26:23]<ries> terrylm: yes it is [03:34:07]<terrylm> Good. I'm just getting my lathe working, purchased it dead. At the point now that every thing works, except the tool turret is not setup in emc, it works though. [03:39:33]<ries> cool [03:45:38]<terrylm> E-stop question: Hitting F1 seems to set something somewhere that does not otherwise get set if the graphical estop button is used. Any idea what it is? [03:46:19]<terrylm> E-stop question: Hitting F1 seems to set something somewhere that does not otherwise get set if the graphical estop button is used. Any idea what it is? [03:56:22]<terrylm> Never mind that last question, it is not doing it now. I must have been confused... again. [03:58:19]<terrylm> How would one get a float converted into a signed 32 int for input into classicladder? [03:59:26]<terrylm> I see the dev version new has a float type in classicladder. Any way to do it in the release version? [04:38:03]<danimal_garage> phew.. finally got my mill back to normal after loosing all my config files [04:38:16]<frysteev> fun [04:38:26]<danimal_garage> tell me about it [04:38:38]<danimal_garage> lost my toolchanger ladder and everything [04:40:07]<danimal_garage> i'm going to back it up a little more often now lol [04:40:15]<danimal_garage> and on a different drive [04:45:11]<ries> Guys, a spindle + motor... should the shield of the cable be grounded at both ends or only at the spindle side? [04:50:12]<frysteev> one of the other typically [04:54:02]<danimal_garage> cradek (or anyone who uses touchy): do you edit programs on your machine alot, and if so, how easy is it compared to a keyboard? [05:08:49]<cradek> touchy doesn't let you write gcode. it assumes you put your gcode programs in the control by using the network [05:09:11]<cradek> but, it very effectively lets you run typical mdi commands [05:33:16]<danimal_garage> hmm [05:33:33]<danimal_garage> i do alot of on-the-machine editing [05:33:51]<danimal_garage> probably should stick with a keyboard [05:34:14]<cradek> I walk 8' to the normal computer with keyboard to write programs [05:34:27]<cradek> also, there's a stool there [05:34:36]<cradek> and a calculator and notepad and pencil [05:34:41]<danimal_garage> haha i'm about 6 feet away... with a stool [05:34:47]<cradek> there you go [05:34:53]<danimal_garage> in fact i'm on that stool now [05:35:45]<danimal_garage> these computers dont see eachother on the network [05:36:10]<danimal_garage> this is a windows box and i havent gotten that far yet [05:36:52]<danimal_garage> i usually use a flash drive [05:37:05]<danimal_garage> which sucks [05:37:21]<cradek> sounds easy enough to fix... [05:37:44]<danimal_garage> priorities lol [05:38:42]<danimal_garage> enclosure swap is done, and pretty much fully recovered after loosing a HDD [05:39:08]<danimal_garage> looks MUCH better [05:39:38]<danimal_garage> and f2 turns on and off all power now, like the lathe [05:39:50]<cradek> neat [05:40:55]<danimal_garage> just need to swap the vari drive for some cogged belts and get an encoder on there and it's "complete" [05:41:08]<danimal_garage> cogged pullies* [05:48:37]<danimal_garage>http://img.photobucket.com/albums/v20/danielwilcox/shizuoka/DSCN0778.jpg[05:49:27]<danimal_garage>http://img.photobucket.com/albums/v20/danielwilcox/shizuoka/DSCN0779.jpg[05:49:59]<danimal_garage> ribbon cables could be a bit neater [05:50:32]<danimal_garage> and there could be a few less chips on the machine/floor lol [05:55:11]<frysteev> danimal_garage: cool [05:55:23]<danimal_garage> thanks [05:56:00]<frysteev> pics of your machine? [05:56:48]<danimal_garage> hold on i'll find one [05:58:38]<danimal_garage>http://smg.photobucket.com/albums/v20/danielwilcox/?action=view&current=DSCN0546.jpg[05:59:03]<frysteev> sexy [05:59:20]<danimal_garage> there's some sheetmetal around the table for coolant containment now [05:59:27]<danimal_garage> thanks! [06:00:58]<danimal_garage> i wanna make a new control pannel for it eventually [06:01:04]<danimal_garage> same with the lathe [06:05:12]<frysteev>http://www.flickr.com/photos/34832969@N03/4330865247/in/photostream/[06:05:15]<frysteev> thats my new toy [06:05:28]<frysteev> and i have a 7x12 lathe im planning to cnc next [06:06:10]<danimal_garage> nice, i'd love to grab one of those mills for engraving [06:06:16]<danimal_garage> cool [06:06:24]<danimal_garage> cnc lathes are fun [06:07:10]<frysteev> ya [06:07:23]<frysteev> the mini lathe sucks working manually [06:07:33]<frysteev> the dials are too small for my hands [06:07:34]<danimal_garage>http://smg.photobucket.com/albums/v20/danielwilcox/hardinge/[06:07:38]<danimal_garage> there's my lathe [06:08:08]<danimal_garage> yea, i could imagine, my 14x42 gets tight too, especially around the cross slide [06:08:29]<frysteev> what kinda stuff do you make? [06:08:39]<danimal_garage> mountain bike parts [06:08:48]<frysteev> swesome [06:08:54]<danimal_garage> u? [06:09:10]<frysteev> im planning on wokring on camera mounts and stuff [06:09:25]<danimal_garage> cool [06:09:34]<danimal_garage> good idea, i need one lol [06:11:17]<danimal_garage> well time for bed, adios [06:11:24]<frysteev> ttyl [09:18:18]<toast_> toast_ is now known as toastydeath [13:17:00]<jt-plasma> ries: yes [13:17:46]<ries> jt-plasma: did you make teh facing.py software? [13:22:02]<jthornton> yes [13:22:38]<jthornton> I'll only be here for a min or two heading for Herman, Mo this morning [13:23:05]<jthornton> * jthornton heads out now and will be back later [13:25:59]<ries> Ahh now I underttand, we will talk later.. I want to make a small modification to the facing code... [13:27:43]<jthornton> no problem modify it all you want [13:54:57]<DaViruz> is it acceptable to mount a DRO glass scale "upside down", that is with the linear seal pointing upward [13:55:39]<DaViruz> i'm very worried about chips accumulating on the seal, but i can't really find a good way to mount it unless i do it that way.. [14:20:50]<andypugh> Upside down doesn't sound like a great plan. [14:22:23]<andypugh> I suppose you need to decide how good the seal looks. Will you be using coolant? [15:31:44]<danimal_garage> that sounds dangerous [15:35:39]<DaViruz> yeah there will be coolant [15:36:07]<andypugh> I think that it would be a "don't do it" then. [15:36:08]<DaViruz> i think i found a way to monnt it the right way, but it will require a very elaborate mount.. :) [15:36:34]<andypugh> Photo? [15:37:11]<DaViruz> i'll take one the next time i'm there [15:37:57]<andypugh> If you can mount it upside down, then I would guess you can mount it right-way-up and fit the slider with a round-the-corner bracket? [15:39:34]<DaViruz>http://media.photobucket.com/image/optimum bf20 dro/bb1401/Optimum Pierre/Y-AxisOptimumBF20.jpg [15:39:41]<DaViruz> stupid firefox [15:39:51]<DaViruz>http://i2.photobucket.com/albums/y46/bb1401/Optimum%20Pierre/Y-AxisOptimumBF20.jpg[15:39:55]<DaViruz> that's how someone else did it [15:40:00]<DaViruz> same machine [15:40:18]<DaViruz> never occured to me that you could mount it slanted like that, hmm [15:41:28]<andypugh> Looking at it, I would mount the scale on the moving part with a static slider. [15:41:43]<andypugh> Saves flexing the wire all the time too. [15:42:37]<archivist> one axis has to flex [15:43:20]<DaViruz> the X scale was really easy to mount and turned out great [15:43:46]<andypugh> OK, so the slider mounts to the bed on a metal leaf, the principle is the same. [15:43:52]<DaViruz> but i guess mounting the slider stationary is a good idea [15:54:09]<danimal_garage> i'm having issues setting my screen res [15:54:59]<danimal_garage> i did sudo displayconfig-gtk and i was finally able to select my monitor and resolution, but it wont save the settings [15:55:56]<danimal_garage> i also see "FATAL module battery not found" in terminal [18:18:01]<danimal_garage> phew, finally got my display configured right [18:18:53]<john_f_> do you mean like the resolution? [18:19:00]<danimal_garage> yea [18:19:30]<john_f_> Ya it took me forever to figure out how to do that [18:19:39]<danimal_garage> pain in the butt, huh? [18:19:53]<SWPadnos> sudo dpkg-reconfigure -phigh xserver-xorg [18:20:06]<SWPadnos> that should do it, if you have the correct monitor attached [18:20:28]<john_f_> Oh now you show us an easy way :) [18:20:28]<danimal_garage> thanks SWPadnos. i'll try that next time [18:20:44]<SWPadnos> that also takes care of viceo card changes [18:20:48]<SWPadnos> video [18:21:04]<danimal_garage> i had to go manually configure the xorg.conf [18:22:07]<SWPadnos> you wouldn't have to with that command, in theory [18:22:32]<danimal_garage> where were you 2 hours ago lol [18:22:50]<SWPadnos> watching a bunch of idiots jump in the lake [18:22:56]<danimal_garage> ha [18:22:56]<SWPadnos> and swim out to the ice [18:23:06]<SWPadnos> Penguin Plunge [18:23:20]<danimal_garage> oh i thought it was bath day [18:23:28]<SWPadnos> the high winds kicked up just in time for the first group to jump in [18:23:29]<danimal_garage> those people are nuts [18:23:34]<SWPadnos> it's 11 degrees here [18:23:40]<danimal_garage> fuck that [18:23:42]<SWPadnos> and there was about a 20 MPH wind [18:23:47]<SWPadnos> yeah, we got cold just watching [18:23:57]<danimal_garage> that's just stupid [18:24:21]<SWPadnos> raising money for the Special Olympics, so it's a good thing overall [18:24:41]<danimal_garage> it's like 62 in here and i'm cold with a hoodie on [18:24:48]<danimal_garage> yea, i guess you're right [18:25:17]<Jymmm> I wish it was 62 in here, also with a hoodie on [18:25:22]<Jymmm> and fingerless gloves [18:25:49]<danimal_garage> i'm in the garage, so no heat [18:25:59]<danimal_garage> thought about getting a space heater [18:26:24]<Jymmm> It's 47 so I turned on the dryer to break thru the dampness [18:26:49]<Jymmm> exhaust hose disconected [18:26:58]<danimal_garage> ha [18:27:37]<danimal_garage> the garage is on the west side of the house, so it doesnt warm up very fast [18:28:08]<danimal_garage> the house blocks the sun [18:28:19]<danimal_garage> not that there's sun today, it's raining [18:29:27]<danimal_garage> when i get some time off i'm going to insulate the garage [18:29:43]<danimal_garage> it'll be the only room in the house with insulation lol [18:29:50]<Jymmm> that's sad [18:29:56]<Jymmm> It REALLY helps [18:30:08]<danimal_garage> i have it in the attic [18:30:48]<SWPadnos> gotta run. see you later [18:30:58]<danimal_garage> the heat only runs maybe 15 minutes a day in the winter, and i dont use ac, so it isnt entirely neccesary [18:31:04]<Jymmm> SWPadnos: enjoy [18:31:05]<danimal_garage> adios SWPadnos [18:31:32]<danimal_garage> i wanna insulate the garage for noise control [18:31:58]<Jymmm> screw noise, MORE HEAT!!! [18:32:24]<john_f_> I have a wall so 1/3 of the garage is well insulated and heated [18:32:34]<john_f_> it about 32 degrees here today [18:32:54]<john_f_> It doen't cost too much to heat my small room [18:33:06]<john_f_> doesn't [18:33:19]<danimal_garage> i dont even notice it in the bill [18:33:47]<Jymmm> Fine, I'll send you ppl my heating bill! [18:33:56]<john_f_> I really don't have a way to tell how much gas is for the garage heat since its all off the same meter [18:34:04]<danimal_garage> it's in with my electric bill, and my electricity usage fluxuates alot, so it's hard to tell [18:34:35]<danimal_garage> Jymmm: you have the option to live in any climate you want! [18:35:05]<danimal_garage> you already live in this crappy state, so why not live in the warmer part of it lol [18:35:38]<danimal_garage> bay area is nice though [18:35:48]<Jymmm> danimal_garage: Send your CC over and I'll take you up on that for the gas, movign expense, and diff in rent =) [18:36:19]<danimal_garage> probably similar in rent, no? [18:37:30]<Jymmm> I doubt it, but if you're sending your CC, I know for damn sure there won't be =) [18:37:54]<danimal_garage> even if the rent is more, you probably save an equal amount in utilities [18:38:34]<danimal_garage> haha, sorry, no CC's, i hate credit. closed them when i got the house [18:39:06]<Jymmm> Fine, just send the deed [18:39:12]<danimal_garage> ha [18:39:32]<danimal_garage> and i'll send my mortgage [18:39:39]<danimal_garage> :) [18:39:53]<Jymmm> Sure, I'll short sale it =) [18:40:18]<danimal_garage> i bought it short sale lol [18:42:08]<danimal_garage> i didnt buy at the peak so i'm safe :) [19:10:52]<andypugh> danimal_garage: Fatal module battery missing is on my startup too. I think that it might just be because the machine isn't a laptop, so has no battery. [19:13:07]<danimal_garage> andypugh: thanks, i found that out when i googled [19:14:15]<Jymmm> cradek: How are these prices (single sided) http://www.elexp.biz/pro_7bs1.htm[19:15:02]<celeron55> it's funny how it says it's fatal as those errors can be completely ignored [19:15:22]<Eric_K> it's fatal for something [19:15:38]<celeron55> it's fatal considering the loading of the exact module 8) [20:35:31]<SWPLinux> Jymmm: it works. yay! [20:36:33]<Jymmm> SWPLinux: cool beans! [20:36:42]<Jymmm> glossy? [20:37:06]<SWPLinux> yep, just like the other one [20:37:19]<SWPLinux> it may be a little brighter, and I think the angles are better on this one [20:37:31]<frysteev> ola [20:37:32]<Jymmm> SWPLinux: brighter is good, you can always turn that down [20:37:39]<SWPLinux> yep [20:37:55]<Jymmm> SWPLinux: It's a bunch of nice kids down there. [20:38:01]<SWPLinux> cool [20:38:12]<SWPLinux> so 23.5 was probably close :) [20:38:32]<Jymmm> she's younger with braces [20:38:35]<SWPLinux> heh [20:38:42]<frysteev> what is the math to figure out the resolution of my machine, if i know the ballshrew info and the stepper info [20:38:47]<Jymmm> the kids that pg'ed it is nice too [20:38:56]<Jymmm> pkg'ed [20:39:11]<Jymmm> he's an led flashlight freak too [20:39:50]<SWPLinux> frysteev: number of microsteps for your driver * number of steps per revolution of the motor / number of teeth on the motor pulley * number of teeth on the screw pulley * number of screw revolutions per unit of travel [20:39:56]<SWPLinux> heh - right up your alle [20:39:58]<SWPLinux> y [20:40:06]<Jymmm> SWPLinux: http://www.falstad.com/circuit/e-index.html[20:40:48]<Jymmm> SWPLinux: Yeah, had to show him DX too [20:40:52]<SWPLinux> (note that the operations should be done in order, that's not the product of several things divided by the product of several other things, it's several things divided be one thing) [20:41:10]<SWPLinux> oh, nice reference there [20:41:12]<frysteev> .09 degrees / 5mm per rev on the ballscrew then. motor is directly coupled [20:41:15]<Jymmm> so you're saying ssubtract? [20:42:31]<SWPLinux> .09 degrees is a strange number. is that due to half-stepping on the driver? [20:42:52]<Jymmm> SWPLinux: you must really love that laptop =) [20:43:20]<SWPLinux> well, it works, and it has all sorts of software set up on it, which I need to use in Dallas next week [20:43:27]<SWPLinux> so replacing it isn't a great thing right now [20:43:49]<SWPLinux> I do plan to get a smaller one some time, for taking on non-business trips [20:43:54]<Jymmm> you coulda got a usb lcd =) [20:44:15]<SWPLinux> remember that USB was flaky on this machine a couple of weeks ago. it seems to have fixed itself [20:44:45]<Jymmm> lol [20:45:18]<Jymmm> SWPLinux: get one of these http://www.thinkgeek.com/computing/usb-gadgets/c609/[20:45:32]<frysteev> ok so my math is telling me that my motor will does 81 steps per mm on axis travel [20:45:47]<SWPLinux> Mac, Win2k, XP, Vista ... [20:46:03]<SWPLinux> I'm betting it's 80 [20:46:07]<frysteev> SWPLinux: 'one of these things is not like the other' [20:46:18]<SWPLinux> .09 degrees is 400 steps per rev [20:46:26]<SWPLinux> 400 steps / 5mm = 80 steps/mm [20:47:01]<frysteev> so i was close ish [20:47:25]<SWPLinux> relatively :) [20:47:38]<frysteev> i was trying to figure out last eveing if it had enough precisous to do pcbs [20:48:18]<SWPLinux> it's probably OK for anything using components you'd expect to hand solder [20:48:36]<frysteev> i just realizied why my bath ws off, there is not 365 degrees lol [20:48:40]<SWPLinux> heh [20:48:45]<SWPLinux> years and years :) [20:49:18]<Jymmm> too much time on frysteev's hands.... [20:49:32]<SWPLinux> thank you, Styx man [20:49:48]<frysteev> Jymmm: oh shush [20:49:49]<Jymmm> :) [20:50:29]<frysteev> motor mount screws have been sourced and arriving this evening [20:50:44]<SWPLinux> ok, time to hit the hot tub. see you later [20:50:50]<Jymmm> frysteev: you're teling me to shush?! I'll show you! [20:51:13]<frysteev> LOL [20:52:05]<Jymmm> mhhhmm hhhmmhh muhhmmmmm [20:52:16]<frysteev> hehe [20:54:29]<frysteev> Jymmm: you wanted to about the ballscrew bearings on my machine no? [20:55:42]<frysteev> they are tobaki [21:12:00]<alidigitalis> andypugh: hey man - finally got the sherline workin... at least i can jog all three motors in each direction... it's a start [21:12:24]<alidigitalis> i'm ecstatic... :) [21:13:10]<alidigitalis> now i need to get each motor running well.... it's very erratic.... [21:18:28]<andypugh> It shouldn't be at all erratic [21:18:55]<andypugh> Are the pulse timings correct? [21:20:17]<andypugh> Perhaps try increasing the step and space times. (what are they set at now?) [21:21:50]<alidigitalis> andypugh: i'll check later - that machine has been recommissioned by my friend for a bit :) anyhow, wanted to thank you [21:23:02]<andypugh> No problem, I like to think if I answer the easy questions it buys me the right to ask hard ones :-) [21:23:23]<alidigitalis> right on man - well the next step for me is going to be **really** fun [21:24:02]<alidigitalis> i've got this 3d scanner and am taking pictures with it... i want to mill those in styrofoam to cast them in aluminum using a small aluminum foundry... this is gonna be rad :) [21:24:30]<alidigitalis> styrofoam is a great medium for my mini mill.... [21:25:23]<andypugh> That does sound like fun. I am considering making a furnace myself, as I have a few brackets to make that would be better starting from castings than solid lumps. [21:26:27]<alidigitalis> it's a great investment - it's taken me a few years to get it right - if you have any questions ask away [21:27:33]<alidigitalis> really you can build a nice one for sue with propane or charcoal for under $100 usd [21:27:39]<alidigitalis> er use [21:28:17]<andypugh> I was looking to make an induction furnace (as backyard casting with gas burners is tricky in a second-floor flat) but I moved house and now have a back garden that the previous owner laid to gravel, which sounds ideal. [21:28:51]<alidigitalis> tear it up man - fwiw i ran my propane furnace on the balcony downtown on a tiny patio [21:29:02]<andypugh> I have a book on making one out of a Flower Pot (as I guess do many others here) [21:29:23]<alidigitalis> it's a very safe procedure mostly [21:30:15]<alidigitalis> i'll tell you the one thing i know - never cast with a mold directly on cement - the air pockets and moisture in wet cement may explode sending molten metal everywhere... [21:30:29]<andypugh> I have done a bit f foundry work, I used to work in a university Metallurgy department, so had access to all the toys. [21:31:17]<alidigitalis> nice - that's a great gig :) [21:32:37]<andypugh> It was. I keep thinking about going back to academia after weeks like we just had at work. [21:34:51]<andypugh> (Something that is my responsibility on paper is delaying production of a new product, supposedly at a cost of $1,000,000 per day. At a time when all the rest of the team of 12 are away for 2 weeks. I am feeling a little overworked) [21:52:59]<Danimal-office> yawn [21:54:00]<frallzor> * frallzor is bored [22:24:11]<tarzan> andypugh, machining related? [22:32:10]<dmess>http://www.youtube.com/watch?v=crFGsZYM5vk[22:37:07]<andypugh> tarzan: Not even slightly. Machining is what I do to get away from work. [22:45:36]<tarzan> never heard Machining was relaxing [22:46:13]<tarzan> with hot chips flying everywhere [22:46:53]<john_f_> It can be relaxing for me to. When its a hobby there is no pressure. [22:47:22]<john_f_> Of course you still have to be careful about what you are doing [22:48:17]<andypugh> Yes, nobody is watching. If you get tangled in the machine, that's bad. [22:49:59]<danimal_garage> or if you spill your beer [22:50:36]<john_f_> Yes. Beer and machining is not recommended [22:50:42]<danimal_garage> ? [22:51:57]<andypugh> Perhaps he is suggesting wine? [22:52:20]<john_f_> ah of course thats different :) [22:52:25]<frysteev> i have put beer bottles in the laser cutter though [22:52:34]<frysteev> ...after drinking the beer [22:53:32]<john_f_> does the laser cut glass nicely? [22:54:02]<frysteev> no.. [22:54:16]<frysteev> but it engraves it and shatters it nicely [22:54:18]<danimal_garage> i would think the beam would go through [22:54:31]<danimal_garage> ouch [22:54:43]<danimal_garage> glass in the linear bearings [22:54:44]<john_f_> frysteev: what can you cut with your laser? [22:56:41]<frysteev> acrylic basically [22:57:01]<john_f_> do you use EMC? [22:58:05]<john_f_> I would like a laser for thin wood or plastic but I don't know anything about them [22:58:18]<frysteev> the laser is fun. [22:58:40]<andypugh> "Do not look into laser with remaining eye" [22:58:48]<frysteev> but its an old 25watt one, it can really only cut acrylic and cardboard, everything else is basicaly engraving [22:59:07]<john_f_> home built? [22:59:42]<frysteev> no [23:02:41]<alex_joni>http://www.dealextreme.com/details.dx/sku.11315[23:04:49]<john_f_> hmm low cost but I think it needs to be about 150X more power [23:06:27]<tarzan> gas laser [23:06:55]<danimal_garage> buy 150 of them and point them through a single magnifying glass [23:07:29]<john_f_> Thas $4500 worth [23:07:29]<andypugh> Just one and a phase-conjugate mirror with x200 gain. [23:08:29]<celeron55> i guess you could draw some stuff on wood with a 200mW laser 8) [23:13:28]<pcw_home> You can get a ~200 mW red laser from a bad DVD burner [23:14:08]<john_f_> I wonder how slow you would have to go to mark wood? [23:14:57]<celeron55> well, probably very slow [23:15:06]<celeron55> but that's what you can do with a cnc! [23:15:34]<john_f_> Yes start it an come back in a few days. [23:16:43]<danimal_garage> found another reason my the home button should be moved. I accidentally hit it when i ment to hit touch off, and almost busted my indicator since it was still in the part [23:17:11]<danimal_garage> not to mention i gotta re-indicate the part again [23:19:58]<dmess> using an indicator as a probe?? [23:21:32]<danimal_garage> i dont use probes [23:22:55]<frallzor> simple tool setter, shoot! [23:23:17]<danimal_garage> ? [23:23:34]<dmess> i installed a machine at my shop Messier-Dowty Ajax.... were nearing a year of perfect parts... 2 scrappers... 1 my fault... 1 the operator D's we wear them as badges of honour... bcz there nothing else [23:24:34]<frallzor> danimal_garage design for one =) [23:24:53]<frallzor> a simple yet capable one [23:25:21]<danimal_garage> i dont wanna use probes, i like indicators better [23:25:49]<frallzor> how come? [23:26:36]<danimal_garage> more peace of mind [23:26:54]<danimal_garage> old habbits die hard [23:27:25]<frallzor> I think ill try to make a simple classic one, plate with known thickness and a cable to the machine and then a cable to the tool [23:28:01]<danimal_garage> wont work if you're not machining metal [23:28:11]<frallzor> it will [23:28:16]<frallzor> plate = metall [23:28:22]<frallzor> tool = metal [23:28:25]<danimal_garage> oh you mean for z [23:28:28]<frallzor> yeah [23:28:45]<danimal_garage> i'm indicating in a round piece of material for xy [23:28:55]<frallzor> ah [23:29:02]<frallzor> lathe =) [23:29:06]<danimal_garage> mill [23:29:21]<frallzor> millathe? :P [23:29:32]<danimal_garage> nope, just mill mill [23:29:38]<frallzor> mill with A? [23:29:45]<danimal_garage> nope [23:29:59]<frallzor> where does the roundness fit in then? [23:30:02]<frallzor> workpiece? [23:30:13]<danimal_garage> round parts [23:30:23]<danimal_garage> need to get xy on center [23:30:37]<frallzor> aha [23:31:02]<danimal_garage> gotta do some deep trepaning, and i dont have the tools to do it on the lathe [23:31:10]<danimal_garage> so i'm milling them [23:33:18]<frallzor> I see [23:46:33]<danimal_garage> launchast radio sucks now... it turns off every hour like pandora, and has a ton more commercials [23:46:51]<danimal_garage> this all started today [23:46:57]<danimal_garage> bummere [23:46:59]<danimal_garage> -e [23:47:19]<danimal_garage> i guess back to pandora for me
